Update DNS

[ganapa2000]

Hi,

I am trying to update the DNS on all the VMs from the list. Now I am stuck, how to update the DNS IP with 192.168.15.100 and 192.168.15.101.

Please help.

Get-VM MyApp1 | Get-NetworkAdapter |

Select-Object @{N="VM";E={$_.Parent.Name}},

   @{N="NIC";E={$_.Name}},

   @{N="Network";E={$_.NetworkName}},

  MacAddress,

   @{N='IP';E={

   $vNIc = $_

   ($_.Parent.ExtensionData.Guest.Net | where { $_.MacAddress -eq $vNIc.MacAddress }).IPAddress -join '|'

   }},

   @{N='DNS';E={($_.Parent.ExtensionData.Guest.Net.DNSConfig).IPAddress -join ', '}}

Current Output

VM	: MyApp1
NIC	: Network adapter 1
Network	: 12_dvs

MacAddress : 00:50:56:97:79:da

IP	: 192.168.3.17
DNS	: 192.168.1.5, 192.168.1.6

I tested again with several combinations, and this works for me.

Is the user member of the Administrators group on the target machine?

LucD,

The user is a domain admin and its present in Administrators Group on the target machine.

The issue is on all Windows Servers 2012 R2 and 2016 Servers. But when I disable the UAC using the registry setting and reboot the server. the script changes the DNS IP.

I don't have any W2K12R2 servers but on my W2K16, where UAC is enabled, it works perfectly.

Not a lot more I can do I'm afraid.

Thanks a lot for your help. I was able to get this script working by creating a local Administrator account. This helped me to change the DNS without disabling the UAC.

As always, you are simply superb. Thanks you very much
